Hello, i have this 8 monthes old PC, my GPU is reaching +90c and pc shutting down from overheating while playing heavy games ( DOOM-AC Syndicate-ROTTR ), i've tried undervolting and tweaking in Wattman but that caused a heavy throttling and FPS drops and the temp was ~85 ( 80-89 ) and i even made the fans run 100% all time and the pc still shutdown from overheating, i've tried DDU'ing tons of time and it didn't work, i always have the latest GPU versions and i even tried older versions,no other things are overheating, i tried cleaning PC too and it didnt fix anything, is my GPU faulty? should i RMA it?, thanks

I just tried what kingfish said, but it didn't work, pc shat down after ~10 mins, in fact i made a FULL FORMAT for pc 2 weeks ago and installed the amd drivers + openhardwaremonitor only ( pc was still clean ) and the same thing happened, so it's sadly not the problem

Your problem is the third party controllers you are using. Asus, Afterburner, Trixx, etc all conflict with AMD/Wattman controls and settings. Delete them. Before you do, use them to set everything back to application default. Set Wattman back to factory default.

I always reinstall the drivers...up to you.

Then set your Power Limit in Wattman to +50 (all the way to the right). Leave all other settings alone. They should all be at 'automatic'. Click 'apply' at the top of the page.
